ABSTRACT

An image capture apparatus displays a live view image that is based on an acquired image, stores image data that is based on the acquired image, and acquires additional information associated with a predetermined subject included in the live view image. The image capture apparatus superimposes the additional information on the live view image and displays the resulting image before the image data is stored, and stores the image data and the acquired additional information in association with each other.

BACKGROUND Field

The present disclosure relates to an image capture apparatus and amethod for controlling the same.

Description of the Related Art

Technology for associating a given subject appearing in an image withinformation regarding the subject has been proposed. For example,Japanese Patent Laid-Open No. 2003-52767 discloses a system that outputsa sheet on which a picture of a patient and a barcode indicating theidentification number of this patient are displayed in association witheach other. Also, Japanese Patent Laid-Open No. 2002-230182 discloses asystem that downloads a picture of a patient from a database based on IDinformation read out from a barcode attached to a wristband of thepatient, and displays the picture on the screen of a terminal.

It is conceivable that an image capture apparatus configured to recordan obtained image of a subject in association with information regardingthe subject is configured as one aspect for associating a subject andinformation regarding the subject. For example, a barcode or the likeassociated with the information regarding the subject is read out andinformation regarding the subject is acquired in advance, and, when theobtained image data of the subject is recorded, the acquired informationregarding the subject can be associated with the image data.

However, in a case where, when an image is obtained, a photographercannot specify the information regarding the subject acquired inadvance, there has been the risk that information irrelevant to thesubject appearing in the obtained image will be erroneously associatedwith the obtained image data.

The image capture unit 100 is a camera unit that converts an opticalimage of a subject into an electrical signal and outputs an image. Stillimage data or moving image data is generated as a result of executingcompression coding processing or the like on an image. The image captureunit 100 includes an image sensor constituted by a CCD image sensor, aCMOS image sensor, or the like. The image capture unit 100 can includean A/D conversion unit configured to convert an analog signal outputfrom the image sensor into a digital signal. Note that the image captureunit 100 can be located external to the image capture apparatus 1 andacquire an image from an external image capture unit 100 via acommunication unit of the image capture apparatus 1.

The database 130 stores a look up table for associating each of aplurality of codes with predetermined additional information (patientinformation in the present embodiment). A “code” is a one-dimensionalcode such as a barcode or a two-dimensional code such as a QR Code®, andis an identifier in which numerical values or letters are expressedusing a figure. The look up table is for associating patient informationwith numerical values or letters read from a code. An example of thecode is a barcode attached to a wristband worn by a patient, and patientinformation associated with a barcode includes the ID number or name ofthe patient. Note that the database 130 can be located external to theimage capture apparatus 1, and the information acquisition unit 140 cansearch the database 130 via a network or a communication line, andacquire patient information.

The information acquisition unit 140 has the functions of searching thedatabase 130 based on the numerical values or letters read from a codeappearing in the image acquired by the image capture unit 100, andacquiring the patient information associated with this code from thedatabase 130.

The displaycontrol unit 107 also includes the function of performing control tosuperimpose the patient information acquired by the informationacquisition unit 140 from the database 130 on an image that is based onthe image data acquired by the image capture unit 100 and display theresulting image on the display unit 106. Note that the image dataacquired by the image capture unit 100 is also utilized in a functionfor displaying an image that is based on the image data acquired by theimage capture unit 100 on the display unit 106 in real-time, that is, aso-called live view function.

The recording unit 120 includes the function of recording the image dataacquired by the image capture unit 100 in a recording medium (notshown). The recording medium is a flash memory or the like, for example,and can be attachable to and detachable from the image captureapparatus. The recording unit 120 also includes the function ofrecording the image data acquired by the image capture unit 100 and thepatient information acquired by the information acquisition unit 140from the database 130 in association with each other. Note that there isno particular limitation on a mode in which the image data acquired bythe image capture unit 100 and the patient information acquired by theinformation acquisition unit 140 from the database 130 are recoded inassociation with each other. For example, a method for recording, as onefile, image data to which information data has been added, or a methodfor recording image data and patient information data as separate filesthat are associated with each other using file names or the like can beused.

The control unit 150 includes the function of performing overall controlof the image capture unit 100, the display control unit 107, therecording unit 120, and the information acquisition unit 140.

The functions of the image capture apparatus illustrated in FIG. 1 canbe realized by a hardware configuration shown in FIG. 2, for example.

As illustrated in FIG. 2, the image capture apparatus 1 according to thepresent embodiment includes the image capture unit 100, a CPU (centralprocessing unit) 101, a RAM 102, a ROM 103, a bus 104, an operation unit105, the display unit 106, and the display control unit 107. The imagecapture apparatus 1 includes an image capture control unit 108, adigital signal processing unit 109, an encoder unit 110, an externalmemory control unit 111, and an image processing unit 112. These unitsare communicably connected to each other via the bus 104.

As described above, the image capture unit 100 is a camera unit thatconverts an optical image of a subject into an electrical signal andoutputs the converted electrical signal as image data.

The CPU 101 is a processor that collectively controls constituentcomponents of the image capture apparatus 1. The CPU 101 includes thefunction of the control unit 150. The RAM 102 is a memory functioning asa main memory, a work area, or the like of the CPU 101. The ROM 103 is amemory for storing a control program or the like executed by the CPU101. The bus 104 is a transmission path for various kinds of data. Forexample, the image data acquired by the image capture unit 100 istransmitted to a predetermined processing unit via the bus 104.

The operation unit 105 is a device for the user (photographer) to inputan instruction to the image capture apparatus 1. The operation unit 105is constituted by a power source button, a shutter button, and a modedial, for example. The mode dial is a dial for switching operation modessuch as an information acquisition mode and a shooting mode, forexample.

The display unit 106 is a display device that displays an image,letters, or the like, and is constituted by a liquid crystal display orthe like, for example. The display unit 106 can also include a touchinput function as a touch screen, and, in this case, the touch screenalso corresponds to the operation unit 105. If the image captureapparatus 1 has a finder, the finder also corresponds to the displayunit 106.

The display control unit 107 is an interface for controlling thedisplaying of an image, letters, or the like displayed on the displayunit 106.

The image capture control unit 108 controls the image capture unit 100based on an instruction issued from the CPU 101, through focusadjustment, shutter opening or closing, and aperture diaphragmadjustment, etc.

The digital signal processing unit 109 performs, on the image datareceived via the bus 104, image processing such as white balanceprocessing, gamma processing, and noise reduction processing, forexample.

The encoder unit 110 performs processing for converting the image datareceived via the bus 104 into a file format such as JPEG or MPEG, forexample.

The external memory control unit 111 is an interface for connecting theimage capture apparatus 1 to a PC or a recording medium (for example, ahard disk, a memory card, a CF card, an SD card, a USB memory, or thelike). The image data acquired by the image capture unit 100 and theimage data generated by the image processing unit 112 are recorded in arecording medium (not shown) via the external memory control unit 111.That is, the external memory control unit 111 includes the function ofthe recording unit 120.

The image processing unit 112 performs image processing such asgeneration of a display image, using the image data acquired by theimage capture unit 100 or the image data output by the digital signalprocessing unit 109. Also, the image processing unit 112 analyzes a codeappearing in the image acquired by the image capture unit 100. That is,the image processing unit 112 includes the function of the informationacquisition unit 140.

Next, basic operations of the image capture apparatus according to thepresent embodiment will be described.

The image capture apparatus 1 includes an information acquisition modeand a shooting mode as operation modes. The information acquisition modeis a mode in which patient information associated with a code isacquired from the database 130 based on the code obtained by the imagecapture apparatus 1. The shooting mode is a mode in which image data ofa subject is acquired. The operation mode can be selected via anoperation made by a photographer via the operation unit 105. Note that atransition from the information acquisition mode to the shooting modecan automatically occur in response to completion of acquisition ofpatient information in the information acquisition mode.

FIG. 3 is a flowchart illustrating an example of basic operations of theimage capture apparatus according to the present embodiment. In theprocess from step S301 to step S310 illustrated in FIG. 3, the processfrom step S301 to step S305 corresponds to operations in the informationacquisition mode, and the process from step S306 to step S310corresponds to operations in the shooting mode.

First, in step S301, the image capture unit 100 shoots an image of acode in response to an operation made by the photographer via theoperation unit 105. Herein, a case where a code is a barcode attached toa wristband worn by a patient is presumed as one example.

Next, in step S302, the information acquisition unit 140 reads andanalyzes the code appearing in the image acquired by the image captureunit 100 using a predetermined analysis method, and acquires characterstrings indicated by the code.

Next, in step S303, the information acquisition unit 140 searches thedatabase 130 based on the result of analysis of the code appearing inthe image acquired by the image capture unit 100, and determines whetherpatient information associated with this code is registered in thedatabase 130. In the above-described example, the patient informationregistered in the database 130 includes the ID number or name of apatient associated with information indicated by the barcode, forexample. Note that the information indicated by the barcode can be theID number of the patient, the name or the like of the patient can beregistered in the database 130, and the database 130 can be searched forthe name of the patient based on the ID number.

As a result of searching the database 130, if the information associatedwith the code appearing in the image acquired by the image capture unit100 is not registered in the database 130 (“NO” in step S303), theprocess proceeds to step S304. Then, in step S304, the display controlunit 107 displays a warning message indicating that the patientinformation associated with the code appearing in the image acquired bythe image capture unit 100 is not registered in the database 130superimposed on a live view image displayed on the display unit 106.

FIG. 4B is a diagram illustrating one example of a warning messagedisplayed on the display unit 106. If the patient information associatedwith the code appearing in the image acquired by the image capturingunit 100 is not registered in the database 130, the display control unit107 displays a warning message 421 as illustrated in FIG. 4B,superimposed on a live view image 400. Note that, if the informationassociated with the obtained code is not registered in the database 130,acceptance of a shooting instruction in the shooting mode can beprohibited.

As a result of searching the database 130, if the patient informationassociated with the code appearing in the image acquired by the imagecapture unit 100 is registered in the database 130 (“YES” in step S303),the process proceeds to step S305. Then, in step S305, the informationacquisition unit 140 acquires the patient information associated withthe code appearing in the image acquired by the image capture unit 100from the database 130.

A subject associated with the code obtained in the informationacquisition mode is obtained in the shooting mode. In theabove-described example, the subject is a patient wearing a wristband towhich the barcode is attached.

Next, in step S306, the display control unit 107 displays the patientinformation acquired by the information acquisition unit 140 from thedatabase 130 superimposed on the live view image displayed on thedisplay unit 106 until a shooting instruction to capture an image of asubject is issued in the shooting mode. By displaying the patientinformation superimposed on the live view image, the photographer cangrasp, at a glance, patient information scheduled to be recorded inassociation with the data of an image of a subject to be obtained. Forexample, if there is an error, such as patient information still beingthe patient information regarding the previous subject due to a failurein obtaining an image of a code or acquiring different patientinformation by erroneously reading a code, the photographer can easilynotice that the subject in the live view image does not coincide withthe patient information. The photographer then captures an image of thecode of the wristband worn by the subject again, and the above-describedprocess from step S301 is performed again, and thus the photographer canchange the patient information to correct patient information. Thus, itis possible to prevent a subject and patient information from beingerroneously associated with each other. Note that patient informationcan be displayed on the display unit 106 continuously or intermittently.

FIG. 4A is a diagram illustrating one example of patient informationdisplayed on the display unit 106. If patient information associatedwith the code obtained in the information acquisition mode is registeredin the database 130, the display control unit 107 displays patientinformation as illustrated in FIG. 4A superimposed on the live viewimage 400. The code in this example is a barcode attached to a wristbandworn by a patient, and patient information associated with the barcodeincludes the ID number and name of this patient, for example. Note that,while a thumbnail image 410 of the barcode obtained in the informationacquisition mode, an ID number 411 of a patient, and a name 412 of thepatient are displayed on the display unit 106 in FIG. 4A, the thumbnailimage 410 of the barcode may not be displayed.

Next, the control unit 150 determines in step S307 whether a shutterbutton is half-pressed by the photographer. If it is determined that theshutter button is half-pressed (“YES” in step S307), the processproceeds to step S308. If it is determined that the shutter button isnot half-pressed (“NO” in step S307), the patient information remainsdisplayed on the display unit 106, and the process returns to step S307.Note that the control unit 150 detects an operation made by thephotographer on the shutter button in two stages that are a half-pressand a full-press.

Next, in step S308, the display control unit 107 hides the patientinformation displayed on the display unit 106. It is conceivable thathalf-pressing of the shutter button is an operation indicating that thephotographer has decided a subject whose image is to be obtained, thatis, an instruction to start image capturing is issued. As a result ofhiding the patient information, the photographer can more easily check,on the display unit 106, a subject whose image is to be obtained withoutpatient information being in the way. Note that, while the patientinformation is hidden if it is determined that the shutter button ishalf-pressed in the present embodiment, a configuration can be adoptedin which patient information is hidden as a result of detecting thatanother operation member has been operated instead of the shutterbutton. Also, a configuration can be adopted in which the patientinformation is hidden if a predetermined time period has elapsed afterpatient information is displayed.

Next, the control unit 150 determines in step S309 whether the shutterbutton is fully-pressed by the photographer and a recording instructionto record an obtained image of the subject has been issued. If it isdetermined that the recording instruction to record the obtained imageof the subject has been issued (“YES” in step S309), the processproceeds to step S310. If it is determined that the recordinginstruction to record the obtained image of the subject has not beenissued (“NO” in step S309), the process returns to step S306, and thedisplay control unit 107 displays the patient information superimposedon the live view image displayed on the display unit 106 again. If ashutter button pressing operation is cancelled or a pressing operationis not detected due to the photographer not completing half-pressing,for example, the control unit 150 determines that the recordinginstruction to record the obtained image of the subject has not beenissued.

Next, in step S310, in response to the fact that full-pressing of theshutter button has been detected, the recording unit 120 records theimage data of the subject acquired by the image capture unit 100 in arecording medium in association with the patient information acquired bythe information acquisition unit 140 from the database 130.

The patient information acquired from the database 130 in step S305based on the code obtained in the information acquisition mode istemporarily stored in a memory, such as the RAM 102, as informationscheduled to be recorded in association with image data of the subjectacquired in the shooting mode. When patient information is displayed instep S306, the patient information stored in this memory is read out,and displayed on the display unit 106 together with the live view image.When the image data of the subject is recoded in step S310, the patientinformation stored in this memory is read out as patient informationrecorded in association with the image data of the subject. The patientinformation stored in the memory is rewritten each time the process fromstep S301 to S305 is executed in the information acquisition mode andnew patient information is acquired.

A configuration can be adopted in which patient information stored inthe memory is optionally deleted through an operation made by thephotographer. Patient information stored in the memory can be deleted inconjunction with turning off a power source of the image captureapparatus 1. For example, a configuration can be adopted in which, whenthe power source of the image capture apparatus 1 is turned off, patientinformation stored in the memory is automatically deleted per a settingmade by the photographer. A configuration can be adopted in which, byasking, when turning off the power source of the image capture apparatus1, the photographer whether to delete patient information stored in thememory, the photographer can select whether patient information storedin the memory is to be deleted or stored after the power source isturned off.

FIG. 5 is a flowchart illustrating one example of processing fordeleting patient information when the power source of the image captureapparatus is turned off.

First, the control unit 150 determines in step S501 whether a settinghas been made to automatically delete patient information stored in thememory when the power source is turned off in response to an operationmade by the photographer via the operation unit 105.

As a result of the determination, if a setting has been made toautomatically delete patient information (“YES” in step S501), theprocess proceeds to step S502. In step S502, the control unit 150 thendeletes patient information stored in the memory. Then, the processproceeds to step S503. If no setting has been made to automaticallydelete patient information (“NO” in step S501), the process proceeds tostep S503 without deleting patient information stored in the memory.

Next, in step S503, the control unit 150 turns off the power source ofthe image capture apparatus 1 based on a predetermined shutdownsequence. At this time, if patient information is stored in the memory(“NO” in step S501), predetermined processing for keeping the patientinformation stored in the memory from being lost due to the power sourcebeing turned off is performed as needed, such as moving the patientinformation into a non-volatile memory or the like, for example.

If patient information is stored when the image capture apparatus 1 isturned on, the patient information stored therein can be immediatelydisplayed on the display unit 106.

Next, processing for displaying patient information according to thepresent embodiment will be described.

The image capture apparatus 1 displays the acquired patient informationsuperimposed on a live view image in the patient information displayprocessing in step S306 shown in FIG. 3. At this time, if the imagecapture apparatus 1 acquires patient information again, the imagecapture apparatus 1 can change the position at which the patientinformation acquired again is displayed. By changing the patientinformation display position, it is possible to improve the visibilitythat the displayed patient information has been changed. Note that inorder to improve the visibility that the displayed patient informationhas been changed, instead of changing the patient information displayposition, the display color can be changed, or the patient informationdisplay position and the display color can be changed together.

FIG. 6 is a flowchart illustrating one example of processing fordisplaying patient information in the image capture apparatus accordingto this embodiment. In FIG. 6, a case where the display unit 106 hasthree positions at which patient information is displayed will bedescribed.

First, in step S601, the control unit 150 sets a counter variable i to0. The control unit 150 sets the counter variable i to 0 if theinformation acquisition unit 140 acquires patient information, or if itis determined that the stored patient information is to be initiallydisplayed when the image capture apparatus 1 is turned on, for example.Hereinafter, a case where the image capture apparatus 1 is turned onwill be described as one example.

Next, in step S602, the control unit 150 determines whether patientinformation is to be displayed as (3i+1)th patient information after theimage capture apparatus is turned on.

If it is determined that the patient information is to be displayed as(3i+1)th patient information after the image capture apparatus 1 isturned on (“YES” in step S602), the process proceeds to step S603. Instep S603, the display control unit 107 then displays the patientinformation at a first display position 720 on the display unit 106.FIG. 7A is a diagram illustrating one example of the first displayposition 720 on the display unit 106 at which the patient information isdisplayed.

If it is determined that the patient information is not to be displayedas (3i+1)th patient information after the image capture apparatus 1 isturned on (“NO” in step S602), the process proceeds to step S604. Thecontrol unit 150 then determines in step S604 whether the patientinformation is to be displayed as (3i+2)th patient information after theimage capture apparatus 1 is turned on.

If it is determined that the patient information is to be displayed as(3i+2)th patient information after the image capture apparatus 1 isturned on (“YES” in step S604), the process proceeds to step S605. Instep S605, the display control unit 107 then displays the patientinformation at a second display position 721 on the display unit 106that is different from the first display position 720. FIG. 7B is adiagram illustrating one example of the second display position 721 onthe display unit 106 at which the patient information is displayed.

If it is determined that the patient information is not to be displayedas (3i+2)th patient information after the image capture apparatus 1 isturned on (“NO” in step S604), the process proceeds to step S606. Thecontrol unit 150 then determines in step S606 whether the patientinformation is to be displayed as the (3i+3)th patient information afterthe image capture apparatus 1 is turned on.

If it is determined that the patient information is to be displayed as(3i+3)th patient information after the image capture apparatus 1 isturned on (“YES” in step S606), the process proceeds to step S607. Instep S607, the display control unit 107 then displays the patientinformation at a third display position 722 on the display unit 106 thatis different from the first display position 720 and the second displayposition 721. FIG. 7C is a diagram illustrating one example of the thirddisplay position 722 on the display unit 106 at which the patientinformation is displayed.

If it is determined that the patient information is not to be displayedas (3i+3)th patient information after the image capture apparatus 1 isturned on (“NO” in step S606), the process proceeds to step S608. Thecontrol unit 150 then adds 1 to the counter variable i in step S608, andthe process returns to step S602. Thereafter, the process from step S602to step S608 is repeated until the patient information display positionis determined. That is, after the image capture apparatus 1 is turnedon, the first patient information is displayed at the first displayposition 720, the second patient information is displayed at the seconddisplay position 721, and the third patient information is displayed atthe third display position 722. The fourth patient information isdisplayed at the first display position 720 again, and the displayposition is changed in order for the fifth patient information andonward. By changing the patient information display position, it ispossible to grasp at a glance that patient information has been changed.

In this manner, according to the present embodiment, when an obtainedimage and information regarding a subject are recorded in associationwith each other, it is possible to prevent the subject and informationfrom being erroneously associated with each other.

Other Embodiments

The present disclosure is not limited to the above-described embodiment,and various modifications can be made.

For example, the image capture apparatus 1 can further include a faceauthentication function. If acquired patient information ispre-registered in association with face image data of a patient, theimage capture apparatus 1 collates the face image data with the face ofa person appearing in the live view image, and upon determining that thepatient is another person, issues a warning. For example, a case will bedescribed as one example where, when the image capture apparatus 1stores, in the memory, patient information regarding a person A that ispre-registered in association with face image data of the person A, andan image of a person B is obtained and is displayed as a live viewimage. In this case, the image capture apparatus 1 collates the faceimage data of the person A with the face of the person B, determinesthat the person B is another person, and issues a warning. Thus, thephotographer can prevent the patient information regarding the person Afrom being erroneously recorded in association with the obtained imagein which the person B appears.

While the above-described embodiment has been described assuminginformation that is recorded in association with obtained image data ofa subject is patient information associated with a code, thumbnail imagedata of the code can also be recorded in association with the obtainedimage data of the subject.

While the above-described embodiment has been described assuming thatthe subject is a person, the subject does not necessarily have to be aperson provided that a subject is associated with a code obtained in theinformation acquisition mode.

The above-described embodiment has been described assuming that thedisplay unit 106 has three display positions at which patientinformation is displayed, but the number of patient information displaypositions is not necessarily three.

Embodiments can also be realized by a computer of a system or apparatusthat reads out and executes computer executable instructions (e.g., oneor more programs) recorded on a storage medium (which may also bereferred to more fully as a ‘non-transitory computer-readable storagemedium’) to perform the functions of one or more of the above-describedembodiments and/or that includes one or more circuits (e.g., applicationspecific integrated circuit (ASIC)) for performing the functions of oneor more of the above-described embodiments, and by a method performed bythe computer of the system or apparatus by, for example, reading out andexecuting the computer executable instructions from the storage mediumto perform the functions of one or more of the above-describedembodiments and/or controlling the one or more circuits to perform thefunctions of one or more of the above-described embodiments. Thecomputer may comprise one or more processors (e.g., central processingunit (CPU), micro processing unit (MPU)) and may include a network ofseparate computers or separate processors to read out and execute thecomputer executable instructions. The computer executable instructionsmay be provided to the computer, for example, from a network or thestorage medium. The storage medium may include, for example, one or moreof a hard disk, a random-access memory (RAM), a read only memory (ROM),a storage of distributed computing systems, an optical disk (such as acompact disc (CD), digital versatile disc (DVD), or Blu-ray Disc (BD)™),a flash memory device, a memory card, and the like.
